HENRY E. LEONARD, OF BRQOKLYN, NEW YORK, ASSIGNOR TO U. B. COTTRELL 8;SONS COMPANY, OF NEW YORK, N. $5., A CORPORATION OF DELAWARE.

SHEET-REGISTERING DEVICE.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed December 15. 1917. f Serial No. 207,338.

To all whom it may concern:

Be it known that I, HENRY E. LEONARD, a citizen of the United States,and resident of the borough of Brooklyn, in the city and State of NewYork, have invented a new and useful Improvement in Sheet-RegisteringDevices, of which the following is a specification.

The object of my invention is to provide I10\ el means for registeringsheets, which means include a rotary carrier having thereon sheetgripping and registering devices 'whereby the sheets may be accuratelyregistered on the carrier without stopping the sheets and before thegrippers are caused to close on the sheets; said devices beinginterconnected.

The gripping and registering devices are.

mounted on a common axis and the registering device preferably has ayielding lost motion connection with the gripping device so as to permitthe grippers to close on the sheets after the registering fingers havereached the limit of their forward or registering movement.

A practical embodiment of my invention is represented in theaccompanying drawings in which,

Figure 1 represents in top plan, so much of a sheet handling mechanismas will give a clear understanding of my invention, the parts being inthe positions which they assume when the registering device is at thelimit of its registering movement and the grippers are closed.

Fig. 2 is a section taken in the plane of the line ITII of Fig. 1.

Fig. 3 is a detail section taken in the plane of the line III-III ofFig. 1.

Fig. 4 is a detail section taken in the same plane as Fig. 3, with thegrippers open.

Fig. 5 is a detail section taken in the plane of the line V-V of Fig. 1,and

Fig. 6 is a detail section in the same plane as Fig. 5, with thegrippers open and the registering fingers at the limit of their rearwardmovement.

The rotary carrier is denoted by 1, its shaft by 2, and the frame by 3.The usual cutaway portion 4: is provided in the rotary carrier forpermitting the operation of the gripping and registering devices.

The gripping device comprises the grippers 5, their rocking rod 6suitably mounted in the ends of the rotary carrier, which gripper rod isshown as provided with the usual tw0-armed lever 7, 8, the arm 8 beingprovided with a stud or roller 9 arranged in position to be engaged bythe cam 10 on the frame 3 to open the grippers. The arm 7 is providedwith the usual rod 11 sliding through the stud 12 and the spring 13interposed between the stud 12 and the collar 14, tending to rock therod 6 to close the grippers 5.

The registering device is herein shown as a set of fingers 15 havingsheet engaging ends 16, said fingers being loosely mounted on thegripper rod 6 and having a lost motion connection therewith throughelongated slots 17 in the fingers and screws 18 passing through saidslots into engagement with the gripper rod. A coil spring 19 surroundsthe rod 6 and has one end engaged with the gripper 5 and the other endengaged with the registerin finger 15, tending to hold the registeringfinger at the limit of its forward or registering movement, the springpermitting a lost motion connection between the gripping device and theregistering device so as to permit the grippers to close on the sheet orsheets after the registering fingers have reached the limit of theirforward movement.

In operation, as the sheets are fed onto the rotary carrier, the headsof the sheets will be engaged by the registering fingers and the sheetsproperly registered by the forward movement of the registering fingersjust before the grippers in their forward movement are closed onto thesheets. This result is being accomplished during the rotary movement ofthe carrier, thus obviating the necessity of stopping the sheets ontheir way to the carrier and also facilitating the rapid handling of thesheets.

Ttis evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, and hence'I do notwish to limit myself to the structure herein shown and described, but

What I claim is:

1. A rotary sheet carrier, a rocking gripper rod, grippers fixed to rocktherewith, registering fingers having a limited rocking movement on saidrod, and spring means forming a yielding connection between said fingersand grippers.

2. A rotary sheet carrier, a rocking gripforward or registeringmovement, to permit per rod, grippers fixed to rock therewith, thegrippers to close after the fingers have 10 registering fingers looselymounted on said reached the limit of their forward moverod and having alost motion connection ment. therewith, coil springs surrounding saidrod In testimony that I claim the foregoing and having their endsengaged with the as my invention I have signed my name grippers and thefingers respectively, tendthis tenth day of December, 1917. ing to holdthe fingers at the limit of their HENRY E. LEONARD.
